This is an inheritance model developed based on studies from Houston (1979) in the inheritance f the color pattern of Coelophora inaequalis and from Pruchova et al. (2014) on visual warning signals of the ladybird H. axyridis.

HOW IT WORKS
HOW IT WORKS
1. Dominance order and codominance involving four alleles in a locus: cs, cn, cb, and cv. See details in the related model Multi-allelic and Codominant Inheritance (https://sites.google.com/view/3d-science-abm/genetics#h.p_6Ewihtv9sEMM).
2. Genetic drift due to randomization of passing an allele to offspring.
3. The predatory birds tend to avoid the bright red phenotype, which is associated with the genotypes of cncn and cncb.
THINGS TO TRY
THINGS TO TRY
Genetic drift: Turn off birds. Test the genetic drift among two, three, and four alleles. Explore how population size affects genetic drift.
Interplay between drift and selection: Turn on birds. Test the interplay between genetic drift and natural selection.
